Include Postgres command helpers

[morrislaptop]

The command utilities like createdb and pg_restore are very handy.

In fact, if you've used Laravel Schema Dump, they will no longer work as it relies on these commands to exist..

The solution is to brew install libpq and brew link libpq --force but I was really looking forward to not using Homebrew anymore!

The service binaries are located at /users/Shared/Herd/services/...
You might need to manually add a folder to your path.
We already symlink a couple of binaries when installing PostgreSQL but not all of them.
